Working with 1GB local model changing many Panel layouts. When we tried to update the changes to the Group Model, CA Plex generated GPF without the 64-bit option. However, with the 64-bit option it updated without any issues. The benefit for this case is that all the work didn’t get lost.

Generation performance, CA Plex slowed down drastically generating sources when the memory usage (from Task Manager) is near 1.8 or 1.9 GB, due to 2GB is a limit of 32-bit application. However, with the 64-bit option, CA Plex does not slow down and consumes over 2GB of memory.

CA Plex can generate more functions without crashing.

Lastly,

This isn't a memory leak fix. It is only giving a longer life to the Plex.exe. We haven't observed yet, but in theory it will crash if it consumes near 4GB of memory.

The threat here, is that the loss of your work could be larger if you don't save the local model often.
